About ADP
ADP is the largest payroll and HR provider in the US, serving everyone from one-person businesses (through ADP RUN) to global enterprises (through ADP Workforce Now). It offers full-service federal, state, and local tax filing, W-2 and 1099 generation, new-hire reporting, multi-state payroll, integrated workers compensation, and benefits administration, backed by decades of compliance depth and a large support organization. Pricing is quote-only with no public price list, scaling by headcount, plan (Essential, Enhanced, Complete, HR Pro), and how much HR you add, so it shows as Get quote here. ADP is strong on compliance and scale but can be more complex and costly than self-serve SMB tools.
ADP was founded in 1949 and is headquartered in Roseland, USA.

Common questions about ADP
The same questions US merchants ask before signing up.
ADP pricing is entirely quote-based, with a per-employee-per-month fee plus per-payroll-run charges and add-on module fees. There is no published self-serve rate card; cost is scoped during a sales conversation and varies by product (ADP Run for small business, Workforce Now for mid-market) and the modules you add. Expect an enterprise-style sales process rather than instant checkout. The comparison table notes ADP as quote-only.
ADP Run targets small businesses and bundles payroll, tax filing, and HR basics, while ADP Workforce Now serves mid-market companies with deeper HR, benefits, talent, and analytics. ADP also runs a PEO, ADP TotalSource, for businesses that want co-employment and pooled benefits. This range is why ADP scales from a few employees to large enterprises, though it can feel heavier than a focused small-business tool.
Yes. Comprehensive payroll tax compliance is ADP's core strength, including multi-state and local tax handling, full ACA tracking and filing, and digital I-9 with E-Verify. For companies with employees spread across many states or complex tax situations, ADP's depth here is a significant advantage and a common reason larger businesses choose it over lighter platforms.
Yes. ADP TotalSource is ADP's PEO, providing co-employment, large-group benefits, workers' compensation, and outsourced HR and compliance, similar in concept to Justworks but backed by ADP's scale. Businesses can choose between the software-and-payroll products and the full PEO depending on how much employment administration they want to hand off. Pricing for either path is quote-based.
Yes. ADP includes native AI (ADP Assist) for surfacing insights, answering questions, and flagging anomalies across payroll and HR data, drawing on its large dataset. It does not publish a first-party MCP server; AI agents connect through third-party and community integrations or ADP's APIs. The AI is geared toward data insight and compliance assistance rather than open agent tooling.
It can be. ADP scales from small businesses (via ADP Run) to large enterprises, but the quote-based pricing, per-run fees, and breadth of modules can feel heavy for a simple small team. Many small US businesses find Gusto or Justworks more approachable and transparent. ADP makes the most sense when you need deep payroll-tax compliance, broad HR capability, or a clear path to scale into the mid-market and beyond.
